Project description:Experiment evaluating aplicability of PlasTi-microarray for cross-species hybridization studies. PlasTi-microarray is a tiling oligonucleotide microarray originally designed for cucumber plastome analysis.Chloroplast RNA from Arabidopsis, tomato and spinach leaves was extracted, labelled and hybridized to PlasTi-microarray with the cucumber samples labelled with the second dye as a control. For each species, one biological sample and one technical replicate (labelled in a dye-swap orientation) were analyzed, resulting in two microarray hybridizations per species and six microarrays (a-f) in total.
